"The ypresent invention relates to the packaging, dispensing ,andfeeding of grit, feed, `and the like for live- Jst'ock, particularly forpoultry.

.aging means and as a feeding trough.

Such combined containers and feeders'have been heretofore attempted, andalthough those known to me have been operative, they are of suchcomplicated construction as to be prohibitive from the point of view ofcost.

A further objective, therefore is to provide a containerfeeder of simpleconstruction and low cost.

The present invention provides a combined packaging and dispensingcarton and feeding trough that can be made or set up complete from asingle blank stamped from a sheet of cardboard or other suitable sheetmaterial.

When the said single blank is folded and secured, it forms a cartonhaving four vertical walls and a bottom closure. The bottom closurecomprises a rst panel hinged to the bottom of the front wall and eX-tending to the rear wall to form the inside bottom surface of thecarton, a second panel hinged to the bottom of the rear wall andextending underneath the rst panel to a position below the front wall, atrough-forming panel hinged to the front edge of the second panel andextending upwardly therefrom in front of the front wall, two end apshinged to the two ends, respectively, of the trough-forming panel, twovertical slots in the Walls at the front corners of the carton toreceive the two end flaps, respectively, stopmembers on the end flaps toengage the walls when the flaps are partially withdrawn from the cartona given distance, and two side closure flaps hinged to the bottom edgesof the two side walls,

respectively, each extending across the bottom of the carton underneaththe second panel toward the opposite side wall to form the outsidebottom surface of the carton. At least one aperture is provided in thefront wall opposite the trough-forming panel to permit the contents ofthe carton to flow into the trough that is formed between the front walland the trough-forming panel when the end flaps are partially withdrawnfrom the carton.

An illustrative embodiment is described below and shown in theaccompanying drawings, in which:

Figure l shows a closed carton in use as a packaging means for poultrygrit or feed;

Figure 2 shows the carton of Figure 1 in readiness for use as a feeder,with the feeding trough open;

Figure 3 is a vertical sectional view of the lower por- Tice 2 tionofthe carton, showingthe trough in closed position (solid lines) an'd inIopen position (dotted lines);

Figure :f4 shows `the single blank from which the carton .isformedg andFigures 5, 6, 7 and 8 show successive ystages in the formation of thecarton from the blank.

HThe carton has four vertical walls, namely, a front .wail 15, a rearwall 16, .a left sidewall 117 and a right side wall '18. A 'fasteningflap 19 hinged to the right edge -of the front wall 15, is glued,stapled or otherwise `fastened to the frontmargin .of the right sidewall 18 when the blank of Figure 4 "is folded into the `form shown YinFigure '5. Conventional fulloverlap V.glue-seal closure iiaps 2l) areprovided at the top.

A iirstpanel '25, hinged at `26 to the bottom of the front wall 15,extends tothe rear wall 16.and is secured thereto by a fastening `flap27, to form the inside bottom surface `of the .carton A second panel 28,hinged at '29.to the bottom of the rear wall 16., extends underneath thefirst panel 25 to a ,position below the front wall 15. A trough-formingpanel 30, "hinged at 31 to the front edge of the second panel 28,extends `upwardly therefrom in front of the front wall 15. Two end ilaps32, hinged at 33 to the two ends, respectively, of the trough-forming.panel 30, extend into the carton through `two slots '34 and 35,respectively, inthe walls at thefront corners of -the carton, to 'formthe end walls of `the trough.

Referring to Figure 3, the top edges 36 of the trough end flaps 32 arearcuate about the hinge 31, the radius of the arc being `of a length topermit clearance of the tops of the slots 34 and 35 by the edges 36 asthe trough is opened and closed in use.

The rear portions of the trough end flaps 32 are shaped to extendupwardly above the arcuate top edges 36 to form stop members 37 forengagement with the inside surface of the front wall 15 after the flaps32 are partially withdrawn from the carton a given distance when thetrough is opened.

In making or assembling the carton, the folding of the second bottompanel 28 into its permanent position as a part of the oor or bottom ofthe carton, and the insertion of the trough end flaps 32 through theslots 34 and 35, are performed as a single operation following the stepthat is shown in Figure 6. At this point in the assembly process, theside closure flaps 40 are not yet in position, so that the trough endflaps 32 can temporarily extend downwardly between the side edges` ofthe rst panel 25 and the respective side walls 17 and 18 a sumcientdistance to permit the tops of the stop members 37 to clear the tops ofthe slots 34 and 35 (Figure '7), as'the flap 28 and the attached vtroughmembers 30 and 32 are being moved into their respective positions in thefinished carton.

Thereafter a strip of tape 42 is alixed to hold the trough shut, and thetwo side closure aps 40 which are hinged at 43 to the bottom edges ofthe left and right side walls 17 Vand 18, respectively, are then foldedinto position (Figure 8). The flaps 40 extend across the bottom of thecarton underneath the second panel 28 toward the respec tive oppositeside walls 17 and 13, to form the outside bottom surface of the carton.

The carton is then filled with the grit, feed, or other flowablematerial, the top closure flaps 20 are fastened in position, and thecarton is ready for shipment and storage (Figure 1).

`When the grit or other material s to be fed, the tape 42 is removed (orslit, as by a suitable tear string) and the trough is opened (Figure 2),whereupon the grit flows into the trough through the one or more`apertures 45` that are provided in the lower portion of the front wall15, these apertures being in a position to be covered by -thetrough-forming panel 30 when the trough is shut.

The panels 30 and 15 lform the front and rear walls 'of the open'trough, respectively, the flaps 32the end thescope of the inventiondescribed and/or claimed herein. n
